FAUCET.

Specification of Letters Patent No. 17,438, dated June 2, 1857.

To all whom it may concern:

Be it known that I, LUcIUs J. KNoWLEs, of lVarren, in the county of lVorcester and State of Massachusetts, have invented an Improved Self-Closing Faucet, and do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure l is an external elevation of the said faucet; Fig. 2, a vertical, central and longitudinal section of it; Fig. 3, an external view of its valve and stem as separate from the body of the faucet. Fig. 4 is a longitudinal section of the said body as separate from the valve and stem. Fig. 5 is a top view, and Fig. 6 an underside view of the faucet as it appears when closed.

In the drawings, A, denotes the body of the faucet, as provided with a screw a, by which itmay be inserted in a barrel or other vessel for holding a liquid, such body being provided with an eduction passage l), having a right angular bend for the purpose of discharging a liquid directly downward. The valve stem B, plays or slides through the horizontal part of the body and has a conical valve C, fixed on its rear end and so as to rest against a seat formed in the rear end of the body.

Directly in front of the vertical part of the eduction passage and extending around the valve stem, and downward therefrom as shown in the figures, is a secondary chamber or passage, D, whose purpose is to arrest any fluid which would be likely to escape by the valve stem and iow down on the' front part of the outer surface of the body. By this secondary chamber the main educ tion passage is insulated from that part of the outer surface of the body which is directly under the stem, and consequently the pressure exerted on a liquid when it may be running through the eduction passage will be prevented from forcing such fluid out of the passage c, through which the valve stem passes out of the body. Directly in rear of said passage c is a shoulder recess al, or small cylindric chamber made somewhat larger in diameter than the ina-in part c, of the stem. A projection f extended from the stem and formed as a cylinder provided with an annular groove, g, works or slides into the recess, d, and serves as a gate or stop to the passage c. The groove g, operates to prevent and is for the purpose of preventing a liquid from following along on the projection f, and escaping through the passage c.

A spring, L, encircles the stern and a projection, z', from the body and by its action against the head, 7c, and the body serves to close the valve when necessary. The valve may be kept open by means of clutch catches formed on the stem and the part v1 as shown in Fig. G. lVhen the valve is forced backward, its stem, if twined a little, will engage the' catches so as to lock the stein or hold it back. Shoulders Z, m formed respectively on the stem and the projection arrest the back revolution of the stem after it has been unclutched.

I claimj l. Combining with or arranging with respect to the valve stem and eduction passage of the body of the faucet as described, the secondary chamber or drip passage D, the saine being for the purpose or to operate as specified.

2. I also claim arranging an annular groove, g, in that part of the valve stem which slides in and out of the recess d of the body of the faucet, the same being for the purpose as described.

In testimony whereof I have hereunto set my signature.
